(Beaverton, Oregon--September 3, 2014) isovideo announces the launch of their Viarte cluster-based SD/HD to HD/UHD/4K remastering Service for the media entertainment industries. Viarte was one of five winners of the prestigious Game-Changer Awards by the IABM/NAB 2013.

As trends move rapidly towards online content distribution and UHD displays, there are vast quantities of valuable SD assets that can be remastered, instead of sitting on the side-lines due to various technical issues. In addition, potentially valuable interlaced HD video assets can be transformed for the best picture quality redistribution, such as Blu-ray and/or cinema presentation, as well as the most efficient H.264/HEVC compression for online re-distribution.

The four most important remastering processing steps prior to re-encoding are: i) deinterlacing and/or inverse-telecine, ii) frame rate conversion, iii) noise reduction iv) scaling. All four steps can effect the final remastering quality and compression efficiency.

For example, most SD assets have various noise problems, such as a range of film grain sizes, dot-crawl noise, analogue noise, etc. Noise not only degrades the viewing experience, but also significantly increases H.264/HEVC compressed bandwidths and costs for online distribution and storage.

isovideo's remastering services use our proprietary, state-of-the-art Viarte technology. It addresses a variety of file formats with a range of inherited condition problems. In particular, it provides:
  • proprietary GPU-accelerated, highest quality, edge sharpening up/down-scaling/aspect ratio conversion with natural-looking edge enhancement, and absolutely no ringing.

  • unique GPU motion-compensated deinterlacing, with i) 100% original field pass-through without any output filter, and yet with very little visible flicker, and ii) on average 21% H.264/HEVC bit-rate reduction, (up from our previously published average of 17%) when compared with compressing interlaced directly. Together these two attributes provide an objective measure of deinterlacing quality. Our deinterlacing has enabled filmmakers to shoot in ntsc60i and show their film on the big screen, and also on Blu-ray.

  • sophisticated GPU inverse telecine technology hardened and used in over 40 episodes of a TV sitcom. It achieves over 99.9% automation and handles extreme noise variation, random-cadences, mixed and broken-cadences, cross-fades, etc. It does not add unnecessary duplicated frames, and has near 100% perfect scene-change detection.

  • superior GPU motion-compensated frame rate conversion technology converts from any frame-rate to any other (including fractional rates). There are almost no occlusion effects when given clean sources. It has already been used in films such as Ron Howard's concert documentary "Made in America" and Karina Epperlein's new feature-length documentary "Finding the Gold Within" (converting from 1980x1080p29.97 to 1080p23.976). The latter film will be released in the Fall of 2014.

  • breakthrough GPU noise-reduction technology achieves on average over 6db noise reduction, while reducing flicker and preserving details and edges. With our noise reduction and scaling, viewers can enjoy a near immersive viewing experience not normally achieved with SD sources. In addition, there can be significant H.264/HEVC potential bandwidth savings. Preliminary results show about 30-50% file size reduction, depending on content.

"Viarte remastering service could make your valuable SD assets look better than ever before, and save significant H.264/HEVC bandwidth at the same time, a true win-win combination" said Keith Slavin, CTO, isovideo LLC. We can help you deal with any unforeseen corner cases in-house very effectively and efficiently should such situation arise, so you can rest assured your content will be handled correctly. With our cost effective remastering service and several partnering options, content owners can seriously plan their SD/HD asset monetization.
